WAC 296-24-37013

Operations and maintenance.

(1) Spraying. You must not conduct spraying outside of predetermined spraying areas.
(2) Cleaning. You must keep all spraying areas as free from the accumulation of deposits of combustible residues as practical, with cleaning conducted daily if necessary. Scrapers, spuds, or other such tools used for cleaning purposes shall be of nonsparking material.
(3) Residue disposal. You must immediately remove residue scrapings and debris contaminated with residue from the premises and properly disposed of. You must provide approved metal waste cans wherever rags or waste are impregnated with finishing material and all such rags or waste deposited therein immediately after use. You must properly dispose of the contents of waste cans at least once daily or at the end of each shift.
(4) Clothing storage. You must not leave spray finishing employees' clothing on the premises overnight unless kept in metal lockers.
(5) Cleaning solvents. You must restrict the use of solvents for cleaning operations to those having flashpoints not less than 100°F; however, for cleaning spray nozzles and auxiliary equipment, solvents having flashpoints not less than those normally used in spray operations may be used. You must conduct such cleaning inside spray booths and ventilating equipment operated during cleaning.
(6) Hazardous materials combinations. You must not alternately use spray booths for different types of coating materials, where the combination of the materials may be conducive to spontaneous ignition, unless all deposits of the first used material are removed from the booth and exhaust ducts prior to spraying with the second used material.
(7) "No smoking" signs. You must conspicuously post "No smoking" signs in large letters on contrasting color background at all spraying areas and paint storage rooms.
